I was just reading about all the questions on metamucil, etc...and what my docs have used is a combo of things for me. I take 100mg of colace and a senna tab every day. They also prescribed Miralax...which you just mix in liquid (fruit juice works best for me) as it takes on the flavor of whatever you drink. I go back and forth with the miralax because once things get moving...they really get moving and don't stop! When I get that way, I just cut out the miralax for a day or two. Ask your doc about it.
